l Claims.

The invention relates to improvements in lamp fixtures and more particularly to a novelly constructed one-piece electric candle support or arm embodying novel mounting means.

An object of the invention is to provide one piece lamp fixture arms adapted to be held rigidly and securely against turning when mounted in a lamp fixture.

Another object of the invention is to provide a one piece channelled arm embodying structural features adapting it to receive and conceal .electric wires.

Another object is to provide an arm for a lamp fixture assembly which, due to its novel features, will be inexpensive to manufacture and easy to attach to the fixture.

The foregoing and such other objects ofthe invention as will become more apparent as the description proceeds will be more readily understood from a perusal of the following specification, in which reference is made to the accompanying drawing, wherein:

Fig. l is a fragmentary elevational view of a lamp fixture embodying the present invention.

Fig. 2 is a longitudinal sectional view taken through one of the arms and its mounting.

Fig. 3 is a sectional view taken substantially on line 33 of Fig. 2.

Fig. 4 is a bottom plan view of the arm.

Fig. 5 is a vertical sectional view takenon line 5-5 of Fig. 2.

Fig. 6 is a vertical sectional view similar to Fig. 2, showing another arm embodying features of the invention.

Fig. 7 is a vertical sectional view similar to Fig. 6, showing a modified form of arm.

In the drawing like numerals identify corresponding parts throughout the specification.

A known method of manufacturing an electric candle support or arm'and for securing it to a lamp fixture includes, forming a length of tubing into any desired shape and securing it to the hollow body of a lamp, either by threading one end to receive a lock nut or by swedging it.

It further includes the threading of the other end of the tubing toreceive a lamp socket and the securing of a cup to the fitting. In some instances the known method includes the fitting of ornaments over the tubing between its ends and in other instances the ornaments are cast around the tubing.

The known methods are costly and result in a ineificient article but in the method of the present invention expense is eliminated because the cup is cast integral with the arm thereby eliminating the tubing. Consequently, the arm may I The shape the arm is to take is determined by how it is to be mounted. By way of examples, the arm illustrated in Figs. 1 to 5 is arranged to be mounted on the bottom face of .the lamp fixture body, the arm of Fig. 6 is arranged to be mounted in the top wall of the body and the arm of Fig. 7 is arranged to be mounted on the side wall of the body.

Referring more particularly to Figs. 1 to 5 inclusive, the arm II, as best illustrated in Fig. 2, includes an intermediate body portion l2 formed with a top wall It and depending side walls [4. A flange 15 formed integrally with the arm extends inwardly from one end thereof and is provided with a square boss ll. External threads are cast on said end and a hole 2|, communicating with the channel, is formed while casting to provide a nipple I'B.

To mount the arm, the nipple l6 and square boss ll are inserted through a square opening It! in the fixture body 19. A lock nut 20 then is screwed tightly on said end to draw the flange I I5 against the outside face of the body to hold the square boss I! in register with the square within the channelled body portion l2 and are adequately concealed by the side walls l4 and by depending end portions 28 and 29.

, Obviously, arms constructed as described are decidedly less expensive to manufacture than those including brass tubing. It is also obvious that the arms are held rigidly in the body l9 against any turning movement although they may be readily removed for replacement.

The S-shaped arm shown in Fig. 6 is structurally similar to the arm previously described except that in this instance the arm has its two ends extending in opposite directions so that it may be mounted on the top face of the body I9. In this form the cast externally threaded end opening l8, thereby holding the arm rigidly and 3 The substantially straight arm shown in Fig. '7 has its ends disposed at right angles to each other and is adapted to be mounted on a vertical side wall of the fixture body I9. The cast externally threaded end It is also formed open at the bottom to facilitate withdrawal of the core. This arm also requires but one depending portion 29 to conceal the contents of the channelled body.

Although exemplary forms of the improved one-piece cast arm have been illustrated and described it is to be understood that the disclosure is illustrative only and not restrictive and that the invention is to embody such a variety of modifications as will fall within the spirit of the invention and the scope of the appended claims.

I claim:v

1. A lamp fixture comprising, in combination, a fixture body and radial fixture arms, said arms each including an intermediate body portion providing an inverted wire-receiving channel, an externally threaded nipple at each arm end, both said nipples being in communication with said channel and at least one of the nipples being integral with the body portion, a cup integral with the body portion below one end nipple, and an integral boss of non-circular section adjacent the other end nipple, the fixture body being provided with aplurality of openings corresponding in shape to'that of the arm bosses, and said other nipple of each arm extending through a body opening and secured to said body by a securing nut, said arm bosses and openings coacting to prevent turning of the arms upon their securement to the fixture body.

2. A lamp fixture comprising, in combination, a fixture body and radially extending arms, said arms each including an intermediate body portion providing an inverted wire-receiving channel, an integral, externally threaded nipple on one arm end in communication with the arm channel and having a squared boss, the other arm end having a tapped opening therein also in communication with the arm channel, a nipple threaded into said tapped opening, and a cup integral with said body portion and disposed about said tapped end and the nipple associated therewith, the fixture body being provided with a plurality of square openings, the integral nipples each extending through a body opening and secured to the body by a securing nut, the squared bosses each coacting with a square opening to prevent turning of the arms upon their securement to the body.

3. As an article of manufacture, a fixture arm including a body portion providing an inverted channel, an integral, externally threaded nipple on one end ofthe arm in communication with the channel and having a boss of non-circular section, the other end of the arm being formed to provide an opening also in communication with said channel, and a cupped flange integral with said body portion and disposed about said opening.

4. As an article of manufacture, a fixture arm including a body portion providing an inverted channel, an integral, externally threaded nipple on one end of the arm in communication with the channel and having a boss of non-circular section, the other end of the arm having a tapped opening therein also in communication with the channel and adapted to receive a nipple, a cupped flange integral with said body portion and dis posed about the tapped opening, and an integral channel end wall depending from said other end of the arm for concealing the relatively front end of the channel.
